Normally, the working motor will be a little hot. Especially in the case of frequent switching. Therefore, slight motor heating is no problem. If you touch it, it is obviously higher than normal body temperature, and the temperature does not drop after the valve is in a static state for a few minutes. This is an abnormal phenomenon and we need to solve it as soon as possible.
1. Find the reason: abnormal heating or overheating of the motor is because the motor has been active for a long time and cannot be effectively cooled. Therefore, when we find that the motor is very hot, we can use an electric pen to test whether the motor has current. If there is current, it means that the motor is working. This is the cause of the motor overheating.
2. After confirming that the motor is always in working condition, the next step is to find the cause of the problem and the reason why the motor cannot stop working. Electric valves usually have both mechanical and electronic restrictions. Normally, the electronic stopper will lock the main position first. Mechanical limits play a supporting role.
